Multi-scale blur pyramid (1..16x) blended for midtone structure; optional Cineon path and mix.
Clarity builds five blurs sized from the clarity amount (1x through 16x), blends them, then divide/multiply merges against the source for local midtone contrast. Negative clarity flips the path via a Switch.
Optional log (Cineon) bookends and a mix dissolve. More of a multi-frequency clarity stack than a single unsharp.
